Chimitdorzhieva G.D.  TO THE ISSUE OF RESTORATION OF FERTILITY OF DEFLATED DRY STEPPE SOILS (BY THE EXAMPLE OF MODEL LABORATORY TESTS) // Arid ecosystems. 2019. V. 25. № 1 (78). P. 43-48. | PDF

Due to the wide distribution of deflated low-humus chestnut soils in the Trans-Baikal region, a search was made to find the ways for restoration of their lost fertility. Model experiments were carried out using green masses and roots of sidereal crops: alfalfa, sweet clover and rapeseed. The results of the survey showed that the added fresh organic masses increase the carbon content by 32-53% from the unfertile variant, out of the total amount in the soils from the use of green masses of alfalfa and sweet clover by 80%, from their roots by 27-55%,  humus was noted to increase its humate level, and the mineral forms of nitrogen.

Keywords: deflated chestnut soils, laboratory model experiments, application of side rates: alfalfa, sweet clover, rapeseed.
